Wow this looks great. I've never played OSU myself, actually, but I used to watch friends play and listen to a lot of the music. I really like this piece. It's open and vibrant. My only complaint would be I'd want just a little more contrast, mostly on the darkest of the dark colors, where there are shadows, as the whole piece seems to have a subtle pink tint in the shadows, and also be just so slightly blurred -- but that looks like a brush thing. But of course, one can always turn the contrast up on my monitor temporarily. It's really not a problem. The image as a whole is lusciously large and popping. It still looks great!
Also congrats on 1939 votes. That's astounding!
